Truck went in for new tcm and a winter service special. Charged me more than they quoted me for tcm and told me they did me a favour by charging less time even though it takes 10 minutes and it can be done while doing the oil change. They didn’t rotate my tires which were way over due and told me they looked ok. There’s no way you can charge shop time for changing oil and reprogramming a tcm when it’s done at the same time.
